How Do I Keep My Heart

Blessed are the undefiled in the way, Who walk in the law of the Lord! Blessed are those who keep His testimonies, Who seek Him with the whole heart! They also do no iniquity; They walk in His ways. You have commanded us To keep Your precepts diligently. Oh, that my ways were directed To keep Your statutes! Then I would not be ashamed, When I look into all Your commandments. I will praise You with uprightness of heart, When I learn Your righteous judgments. I will keep Your statutes; Oh, do not forsake me utterly! How can a young man cleanse his way? By taking heed according to Your word. With my whole heart I have sought You; Oh, let me not wander from Your commandments! Your word I have hidden in my heart, That I might not sin against You. Blessed are You, O Lord! Teach me Your statutes. I will meditate on Your precepts, And contemplate Your ways. I will delight myself in Your statutes; I will not forget Your word.  Psalm 119 1-12, 16,16
